what is research method
understanding the world in deep understanding
source of research ideas
personal experiences
existing problem
process doing hipotesis
agaw recreate
goal of physiological rresearch
describe exolain predict control
quantitaive data
data number based,countable ,measureeable,sturetured data,statistical analysis,objectives conclusions,survey,experinment
qualitative research
unstructured data,summery,subjective conclusions,interview,focus group.
data that tell us how many,how much,how often in calculations
means variable
any factor or elements that can be changed or varied in astudy
independent variable
research manipulates or changes in an experiments,cause or factor that believe to have an effect on the dependent
dependent variable
observed and measured in response to the changes in the independent variable
realibility
consistency a method measures something,if the same result be consistenly achiebed by using the same methods under the same circumstance,but it doesnt mean validity
realibility
consistency a method measures something,if the same result be consistenly achiebed by using the same methods under the same circumstance,but it doesnt mean validity
validity
how accurately a method measures what it is inended to measure,if research has high validity,hat means it producces results that correspond to real properties
types realibility
test rater,inter-rater-internal consistency
types validity
content,construct ,criterion
probality sample
respondent randomly selected to take part on survey
simple random sample
each member of a population is assigned an identief such as a larged group
stratifield random sample
step up from complexity from a simple random sample but divided into sub group
cluster sample
population is divided into cluster which are unique,yet represent a diverse group
systematic sample
participants are selected to be a part of a sample using a fixed interval for example,5,10,15,20
non probability sampling
when sample is created through a non-random process,this could include a researched a survey link to their friends
convenience sample-
its name implies,this method uses people who are convenient to access to complete a study
snowball sample
recuriting some sample members who in turn recruit people they know to join a sample
quto sample
divided into sub group by characteriestisc such as age or location and target are set for the number of respondent needed from each subgroup age or location
purposove or judemental sample
selection is left up to research and their knowledge of who will fit the study criteria
sample size
for important for getting acurate,it the sample too big is become complex,expensive and time-consuming to run
quantitative
number and satandard question (variables) to ask people,we can then measure relatiy ti est our theory objectiveily process of reseacrh unfolds as theory -research -method -theory
qualitative
like interview and process of reseacrh unfole-research-method-theory
observatiobn
rewatch technique where you obseve participants and phenomena in their most natural settings,as opposed to structured settings like research or fous groups
observation
rewatch technique where you observe participants and phenomena in their most natural settings,as opposed to structured setting like research or fovus groups
you should conduct observation behavior?
see how aprticpants ebhave in a natural settings how real world factor influence behavior desribe a phenomenon
types of observational
naturalistic
participants
structrues
controlled
naturalistiic
occur diretly in the environments where the phenomenan occur,is natural no be a control
particpants
observation someone time like interview,takes notes
structured
make observation like natural settings but with stinulated nvironemnt have a criteria and checklist
controlled observation
research method whetr researches watch particpants in a contained environment such a lobaroty,the environemnet absolutely control by them
advantages of qualitative
insider perspective-details,can identify causem,how people experience of actua human behavior,great the development theory
disadvantages quali
-the collect data is slow progress
-cant apply to large popularion
-data analysis complex expect knowledge of the area to draw meaningful conclusions
-chalenge in valdity and realibility-qualitative heavily on the researchers interpretation of vdata,there a risk of bias and inconsistency.
indirect observation
